could explain how matter appeared in the split-second after the Big Bang.Experiments using the LHC were suspended in September 2008 shortly after a successful start, due to a malfunction of two superconducting magnets and a subsequent helium leak into the tunnel housing the device.
Work to repair and upgrade the collider after the breakdown cost almost $40 million and took more than a year. A system to protect it from such accidents, named the Quench Protection System, was installed, and the first beams were injected into the LHC on November 20 last year.
